To all whom 'it may concern:

Be it known that I, PHILIP W. MOORE, a citizen of the 'United States,residing at of Illinois, have invented certain new and usefulImprovements in Railway-Rail Stays, of which the following is aspecification.

The device of the. present invention relates to a structure adapted tobe positioned upon railway rails, for the purpose of preventing at theterminus of a grade or adjacent switches, and like places; andhafs forits object, to construct a stay which will be lightened by the cuttingoff of superfluous metal, and at the same time, retaining the strengthof the stay so that its usefulness is not limpaired in any degree. j Afurther object of the invention is to provide a broad abutting. surface,which will rest against the rail tie, thus providing a broad'bearingsurface for Jche rail stay against the tie; land another object is toform a head upon one of the members of the stay, which will serve as adriving head, against which a hammer or other instrument strikes whenthe stay is being positioned.

In devices of this character, lbecause of the cheapness' ofconstruction, the reduced -cost of shipment, and ease of handling, theweight of the device enters materially into the practicability ofconstruction. A device which is light in comparison with other devicesof similar nature at present on the market, and which will require lessmetal than such devices, is a step in advancement in the art, because ofthe savings in the various ways heretofore set forth. And a device Ofthis character, which is lightn and cheap of construction, and which atthe same time retains all of the strength and rigidity necessary -for apractical device, is what applicant has designed, and these 4are the.'

' movement of the rail is withstoodby the salient features of thepresentinvention.

The invention further consists 1n the feaparts hereinafter described andclaimed.

Vconstruction of the movable clamping mem- ",LInthedrawings, Figure l isa perspective ofthe completed stay; 1g. 2, a plan view; Fig. 3 a frontelevation of the stay, showing l a rail held therein; Fig. 4, a sideview of the stay; and Fig.l 5, aplan view of a modified ber.

The device, as shown in the drawings, coml prises a fixed clampingmember 6 and a movable clamping member 7. The iXed clamping vmembercomprisesv a body portion 8, having a diagonally extending groove 9formed therein, and is provided with a rail gripping jaw l0. The movablesection comprises a body portion 1l, which terminates in a downwardlyprojecting lia-nge 12, adapted to enter the groove 9 in the fixedvmember 6; and the movable member is provided with a rail gripping jaw13, The fixed member is pro. vided with one or more downwardlyprojecting abutments 14, preferably one at either extremity of the frontedge thereof, which abutments lie, in operation, against a railroad tieand prevent the fixed section G from movement during the creeping of therail. It is against these abutments that the major portion of the strainis communicated, hence, these Surfaces, being of the substantial andbroad nature showinwill remain durable and effective during usage.

As shown in Figs. l and 2, one of the side walls of the fixed member Gis cut away, for a portion of its length to form a diagonally extendingwall 17, and this wall terminates, at one end, adjacent to the edge ofthe diagonally extending slot 9, and 'at its other end adjacent the edgeof the front wall of the .fixed membcr;`and formed in the spaceintermediate the terminus of the wall 17 and the front wall is the railgripping member 10. It will be seen by a study of this construction thata great amount of metal is thus eliminated from the fixed section, butin view of the :fact that no great strain is placed upon the grippingmember 10, tle small gripping surfacashown in this structure -does notimpair in any way the elticiency of the device. It will also be seenthat the abutments 14 arebroad, and upon these surfaces comes thegreatest strain 1n operation. Thisy is because of the fact that thebroadnature and which is 'so sloped or anfront wall of the movable section'is cut away, thus eliminating at this point a quan# tity of superl'luousmetal,` and yet the railgripping property of the section is not in anywayimpaired or decreased.

" In Fig. 5`is shown a modifiedconstruction of the movable clampingmember, in which thel outer edge 20 is cut on a bevel, as atl 21,

cutting away the front corner 22. clamping memberformed in this mannerpossesses several distinct advantages: First, itallows` thedownwardlydepending flange or tongue I12 to be easily engaged with thegroove 9., vThis is`- due -to the fact that the clampingl member as thusfor-med permits of atilting or canting of the member in order to enterfthe tongue 12 into the groove 9, eliminating' any forcing. or drivingsuch as 'is'necessary where the gripping jaw is overhanging along itsentire 1engtli,such forcing or driving being undesirable because itrequires more time and trouble, and frequently re'4 sults in the,opening of the front corner .of the jaw. And secondly, the constructionshown in Fig. feliminates metal andV re#A duces theweight and cost ofmanufacture of the clamp, and at the same time does not impair itseiiiciency asafclamping member.

The operation is`as follows: Upon the' placing ofthe stay on the rail,the movable section 7' will be driven forward until the point has beenreached` where the downwardly depending flange 12V will have traveledsuiiciei'itly in the groove 9 to lock against the `walls. of saidgroove. This will locktlie two sections of the stay together, so thatthe movement or creeping of the rail will carry thetwo sectionstherewith, but

owingto the abutments 14 resting against the tie, the movement of thestay-wi1l be checked, and, as the sections of the stay are tightly 'griping theA rail, the movement ofthe rail will be thus arrested.And"'these abutments being, as shown, of substantial and brdadformation, will oder a large bear# ing surface against they tie andrwillserve'to-A resist any vfuitliei' "mevement of the ra il, thus L fixed;f'

preventing the creeping thereof.

The member is referred-to as a clamping member for the salie 'ofconvenience in description, as in actual operation there lwill, be aslight movement imparted thereto bythe movement ofthe rail. .A v
